ST'OPPER FO'R INKVORI'OTHER BHOTTLESL srnomrcA'rron forming part ofLetters Patent No. 421,667, dated-February '18, 1890. Application filedDecember 20, 1889. Serial No, 334,435. (No modelJ To all whom it mayconcern.-

Be it known that I, JOHN WV. CARTER, of Newton, in the county of'Middlesex and State of Massachusetts, a citizen of the United States,have invent-ed a new and useful Improvement in Stoppers for Ink, orother Bottles, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification,in explaining its nature.

'The invention relates to the stopper for ink or other bottleshereinafter specified.

In the drawings, Figure 1 is a view -in vertical' central section of astopper having the features of my invention. Fig. 2 is a section takenacross the spindle on a line with the barbed teeth thereof. Fig.3 is aView in elevation of the main section of the stopper without thespindle-covering, andFig. 4 is a view in section of thespindle-covering.

" A represents the main portion of the stopper. It is made of glass,porcelain, or'other suitable material; jIt has the extension or end a,which may be of any desired shape, and which forms a thumb or otherpiece by which it is handled, the heador flanged having the annulardepression or recess a and the spindle of, which extends from the centerof' the depression or recess. The spindle preferably has, its endprovided with the thread a, extending about half-way or a little morethan half-way. the length of the spindle from its end and the teeth awhich I "are in the nature of barbs, and which preferably are arrangedspirally upon the line-0f the thread of the screw, each of the teeth ahaving the long tangential surface or edge a enTIlingin an abrupt orsharp shoulder a extending back to the face of the spindle, the

incline a being in the direction in which the 1 spindle would be turnedfor the purpose of screwing it into anything. The stopperfurtherco'nsistsof the section.

B, preferably of cork, althoughit may be of any other resilientmaterial. This "section B is preferably conical in shape. Its upper endfl) is made of/a size to closely fit the recess or depression a and it.has a central hole I) of a size; and depth to receive'the spindle a It.is united to the spindle by screwing the spindle intosaid hole untilthelupper end 1)- against the head or flange a of the section is causedto enter said depression or recess a and to be firmly pressed Cement,glue, or other adhesive substance may be placed in the depression andalso in the hole of the section B to serve to'further unite the saidhead or flange and 'to the the cork or covering is very rigidly securedor shouldered teeth substituted therefor.

to the spindle, and a tight joint is formed between the upper end of thecork and the head or flange a and a fine finish is also provided; Thecork or other material, being forcedinto the recess a as it is applied,is firmlyheld by the side wall of the recess upon the teeth of thespindle; s

I would say that it is not essential that the section B have its lowerend solid, as the hole for the reception of the spindle may extend.

entirely through the same.

- I would say that the section A maybe made of wood or any othersuitable material.

In some instances the screw-thread upon the spindle may be dispensedwith and barbeId t isespecially desirable that the spindle have teeth ofthe character above specified, especially'near the. inner end of thespindle, in

order that the cork may be united to the spindle in such a way that upona turning action of the stopper to remove the cork from the bottle thestopper cannot readily be disengaged from the cork, and as the greateststrain upon the cork is at'its upper end,near the inner end of r. thespindle, it is especially essential that it be provided with barbedteeth at this point.

'. Having thus fully described myinvention, I

claim and desire to secure by Letters Patent of the United States- 1. Ina bottle-stopper, the combination of the. section A having theprojec'tion'or knob, a, the head or flange of, having therecess ordepression of, anda spindle a having a screw-thread a andbarbediorholding teeth j aiwith a spindle-covering section v13,011 corkor other i ilar material, provided with afi hole not extending throughthe cork, which receives the spindle, and havingits upper end held orcontained in said recess or depression a substantially as described.

2. A bottle-stopper having the section A, and thespindle a ,providedwith the screwthread a and barbed or holding teeth a and aspindle-covering section B, of cork or other similar materialsubstantially as described.

3. A bottle-stopper having the section A the head or flange a, providedwith'a recess or depression a a spindle a, having barbed or holdingteeth a, and a spindle-covering section B, of cork or other similarmaterial, substantially as described.
